Description

A block chain expansion processing method, device and equipment

technical field

The present invention relates to the field of communication technologies, and in particular, to a method, device and equipment for expanding the capacity of a blockchain.

Background technique

With the popularity and maturity of Bitcoin, the underlying blockchain technology has attracted widespread attention. Due to its distributed, non-centralized, non-tamperable, and traceable features, various industries have begun to introduce blockchain technology to solve business problems they faced before. From a technical point of view, blockchain is a distributed database system, including core technologies such as cryptography and peer-to-peer P2P networks. From the perspective of chain form, blockchain includes application forms such as public chain, private chain and alliance chain.

Among them, the public chain has the following technical characteristics: 1. Organize nodes based on P2P network; 2. Chain storage of blocks; 3. Adopt a certain consensus mechanism to achieve consistency between nodes; 4. Adopt a certain incentive mechanism to encourage more Multiple nodes join the system. Taking Bitcoin, the typical representative of the public chain, as an example, with the continuous increase of global nodes and the continuous enhancement of the computing power of the entire network, the Bitcoin blockchain faces the severe problem of expansion. First of all, each transaction is recorded on a block, and the block connection into a chain structure determines that the system is essentially a linear order relationship. Second, the block size and the time interval between blocks rigidly determine the number of transactions that the system can accommodate in a unit time period.

However, a block size of Bitcoin is 1MB, and a block is generated in an average of 10 minutes. Assuming a transaction size of 256 bytes, the entire Bitcoin system can only process 4K transactions every 10 minutes. This system capacity greatly limits the application of public chains such as Bitcoin in high-concurrency and high-throughput environments. Therefore, the existing blockchain cannot meet the increasing usage demand.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

Aiming at the problem that the existing blockchain cannot meet the increasing use demand, the present invention provides a blockchain expansion processing method, which can optimize the blockchain networking structure according to the network bandwidth and improve the system capacity.

As shown in FIG. 1 , a method for processing capacity expansion of a blockchain according to an embodiment of the present invention includes:

Step 101, obtain the network bandwidth of itself and adjacent devices;

Step 102: Determine its own device level according to the network bandwidth of itself and neighboring devices, wherein the device level at least includes a first-level device and a second-level device, the first-level device itself and the first-level device and the first-level device. The network bandwidth of at least one device adjacent to the device is the first bandwidth, and the network bandwidth of the second-level device itself and the device adjacent to the second-level device includes at least the second bandwidth, and the first bandwidth is greater than the second bandwidth;

Step 103, informing the neighboring device of the device level, and receiving the device level sent by the neighboring device;

Step 104 , generating a block based on the device level of the device itself and the receiving device.

The blockchain expansion processing method in the embodiment of the present invention is applied to a terminal device, and the adjacent devices are other terminal devices that can communicate with the terminal device based on the network structure. According to the above steps, after acquiring the network bandwidth of itself and its neighboring devices, the terminal device further determines its own device level from the acquired network bandwidth, then informs the neighboring devices of the device level, and receives the information sent by the neighboring devices. Device level, and finally generate blocks based on the device level of itself and the receiving device. In this way, considering the network bandwidth, the security of the block is also guaranteed while the system capacity is increased, and the realization effect is better.

It should be known that, in this embodiment, the terminal device and its adjacent devices are connected to a P2P network as nodes on the public chain, and all nodes can test the network bandwidth of the network where the nodes are located. For example, the two most commonly used network bandwidths are 100Mbps and 1000Mbps. Node A accesses the network with a bandwidth of 100Mbps, and Node B accesses the network with a bandwidth of 1000Mbps. The node temporarily stores the network measurement results locally at the node. The results of network measurements are broadcast among its neighbors.

For example, for the above two network bandwidths, the terminal equipment is called a 100M node and a 1000M node respectively. After receiving the network bandwidth of the adjacent node, there are 5 possible situations:

(1) As shown in Figure 2a, itself is a 100M node, and there is a 1000M node in the adjacent node: mark itself as a second-level device;

(2) As shown in Figure 2b, itself is a 100M node, and there are multiple 1000M nodes in adjacent nodes: mark itself as a second-level device;

(3) As shown in Figure 2c, it is a 100M node, and there is no 1000M node in the adjacent nodes: mark itself as a second-level device;

(4) As shown in Figure 2d, itself is a 1000M node, and the adjacent nodes are all 100M nodes: mark itself as a second-level device;

(5) As shown in Figure 2e, it is a 1000M node, and there are 1000M nodes in the adjacent nodes: mark itself as a first-level device.

After that, the node can broadcast its own equipment level to the adjacent nodes, and of course, the equipment level of the adjacent nodes can also be obtained from the broadcast information of the adjacent nodes. Finally, some 1000M nodes become first-level devices, and 100M nodes and some 1000M nodes become second-level devices. A second-level device may have no or only first-level device adjacent to it. A first-level device is also aware of its adjacent second-level devices. A schematic diagram of the device level of a network is shown in Figure 3, including 5 first-level devices (slash-filled) and 7 second-level devices.

Of course, considering that in a network (such as a P2P network), new nodes often join or leave, therefore, in this embodiment, link connectivity is detected, and when it is detected that the connection relationship with adjacent nodes changes , the device level judgment will be performed again.

In this embodiment, optionally, step 1023 includes:

In the case that itself is the first-level device and the receiving device is the first-level device, generate a block of the first capacity according to a preset speed;

In the case that the device itself is the second-level device and the receiving device is the first-level device, the target speed is determined according to the number of adjacent devices of the first-level device, and the block of the second capacity is generated according to the target speed;

In the case where it is a first-level device and the receiving device is a second-level device, or is a second-level device and the receiving device is a second-level device, a block of the second capacity is generated according to a preset speed; wherein,

The first capacity is greater than the second capacity.

In this way, blocks can be generated in a more reasonable manner according to the terminal equipment itself and the equipment level of the receiving equipment. For the case where it is the first-level device and the receiving device is the first-level device, due to the good network status, a larger data block will better improve the efficiency and improve the system capacity. Therefore, the first level will be generated at the preset speed. A block with a capacity; for the case where it is the first-level device, the receiving device is the second-level device, or the second-level device and the receiving device is the second-level device, due to network limitations, the default The speed of generating blocks of the second capacity; for the case where the device itself is the second-level device and the receiving device is the first-level device, the block generation speed can be increased to achieve the purpose of improving the system capacity. Specifically, according to the first-level device The number of adjacent devices of , determines the target speed, and generates blocks of the second capacity according to the target speed.

Wherein, preferably, determining the target speed according to the number of adjacent devices of the first-level device includes:

According to the formula V=(K*m)*T/M, the target speed V is obtained; wherein, K is the number of second-level equipment in the adjacent equipment of the first-level equipment, m is the second capacity, and T is the preset Set the speed, M is the first capacity.

In this way, the first-level equipment, which is the receiving equipment of the current second-level equipment, can further generate large blocks with high efficiency under the condition of controllable load, and make full use of the first-level equipment to improve the system efficiency.

Assuming that the preset speed is 10 minutes/block, the block of the first capacity is a 10M block, and the block of the second capacity is a 1M block, specifically:

Between two first-level devices, due to the good network status, 10M block can be used as the largest block, and 10 minutes/block can be used to generate blocks;

Between the first-level equipment and the receiving equipment is the second-level equipment, due to network limitations, 1M block is used as the largest block, and 10 minutes/block is used to generate blocks;

Between two second-level devices, use 1M block as the largest block, and use 10 minutes/block to generate blocks;

Between the second-level device and the receiving device is the first-level device, since there are 4 devices connected to the first-level device in the network, through the formula V=(K*m)*T/M, the target speed can be obtained= (4*1)*10/10, which is 4 minutes/block, using 1M block as the largest block.

It should be noted that, in this embodiment, the preset speed is mostly a fixed value, and the block generation speed of the entire network as a whole may not be reduced, so that the security of the data is basically the same as before the transformation. Of course, if the network conditions allow, the preset speed adjustment can also be performed for the network.

It should also be known that, in this embodiment, the block of the first capacity encapsulates a plurality of blocks of the second capacity, and the block of the first capacity includes a large block identifier.

In this way, as shown in FIG. 4 , a plurality of blocks of the second capacity are encapsulated in the block of the first capacity, and the blocks of the second capacity can be stored in the form of a linked list. Since the block of the first capacity includes a large block identifier (which can be added to the block header), it is easy to identify the block of the first capacity. When the large block needs to be split into a block of the second capacity, The encapsulated blocks of the second capacity can be taken out in sequence.

Optionally, the block of the second capacity includes a block encapsulation identifier, and the block encapsulation identifier is used to indicate the source of the block.

As shown in Figure 5, the block of the second capacity is added with a block encapsulation identifier (which can be added to the block header) for indicating the source of the block itself, so that the block encapsulation identifier can be used to know the Whether the block is generated by the second-level device, or decapsulated from the block of the first capacity. Because the difficulty of the two is different.

In addition, in this embodiment, for the transceiving of the generated block, the method includes:

If it is a first-level device and receives a block from the first-level device, it directly forwards the received block to the first-level device in the receiving device, and after decapsulating the received block, forwards the block. to secondary equipment in the receiving equipment;

If it is a first-level device and receives a block from a second-level device, it directly forwards the received block to the second-level device in the receiving device, and encapsulates the received block to obtain the first capacity After the block, it is forwarded to the first-level equipment in the receiving equipment;

If it is a second-level device, it forwards the received block to the receiving device.

Here, for the sending and receiving rules of the first-level device, for the block received from the first-level device, it is to directly forward the received block to the first-level device in the receiving device. After encapsulation, it is forwarded to the second-level device in the receiving device; for the block received from the second-level device, the received block is directly forwarded to the second-level device in the receiving device. After the block encapsulation obtains the block of the first capacity, it is forwarded to the first-level device in the receiving device. For the sending and receiving rules of the second-level device, the received block is forwarded to the receiving device.

Generally speaking, in public blockchains, there is an incentive mechanism to encourage more nodes to participate in the system and get rewards while serving the system. Therefore, in this embodiment, the method further includes:

Determine the corresponding forwarding incentives according to the device levels of the device itself and neighboring devices.

Optionally, determining the corresponding incentives according to the device levels of the device itself and neighboring devices, including:

If it is the first-level equipment, the excitation Q ₁ is obtained according to the formula Q ₁ =(S-s)*T/S;

If it is a second-level device, the excitation Q ₂ is obtained according to the formula Q ₂ =s*T/S; among them,

S is the block-producing speed of the first-level equipment; s is the block-producing speed of the second-level equipment; T is the preset basic excitation.

In this way, through the above formula, appropriate incentives can be given to devices of different grades. Of course, the specific incentive methods are not limited to the above content, and will not be listed one by one here.

To sum up, the blockchain expansion processing method according to the embodiment of the present invention, after obtaining the network bandwidth of itself and its adjacent devices, further generates blocks based on the obtained network bandwidth, which can optimize the area according to the network bandwidth status. The blockchain networking structure increases the system capacity; allows the blocks on the blockchain to have different sizes, and the terminal device makes decisions based on network conditions; high-bandwidth nodes can obtain additional incentives when forwarding large blocks to maintain the overall fairness of the system.
